bud I can answer 2 of your questions. I have (3) Tikka T3's and have had absolutely no cycling issues but my rifles are chambered in 260 rem,7mm-08 rem and 6.5x55 swede so not sure about Tikkas and the sharp wizzzzzm shoulder. I absolutely love mine and have had no issues with no bad experiences. I've never even had mag issues but don't hunt in sub 0 degree weather either like some of these guys do.
